All the racers were tire queers nobody running the OEM tires?
I havent done a lot of mud but the OEM tires on my RZR work perfectly for everything I have thrown at them not once have I thought wish I had more traction or actually needed more.
Taller tires would be great for rutted up worn out trails they are racing on
Never understand why morons mount nerfs and bumpers like that straight on with the frame nothing to give, straight on is ok if your mount is weak enough its going to bend before the frame does, I prefer mounting tabs off to the side of the frame to reduce the chances of frame damage, I always thought bumpers and nerfs are designed to absorb some of the impact energy hopefully enough where the main body or frame never sees damage but sooner or later you exceed the capacity of the bumpers or nerfs and all are damaged.
You planning on entering a GNCC race in the future?
Too brutal for me after reading race reports from the past where side by side guys full on ram the guy in front of him if going too slow I would end up in a psychical confrontation and probably in jail if this happen to me.
